- Sampling private wells at past homes to estimate arsenic exposure: a methodologic study in New EnglandJoanne S Colt
Occupational Epidemiology Branch, Division of Cancer Epidemiology and Genetics, National Cancer Institute, Bethesda, Maryland 20892 7240, USA
J Expo Anal Environ Epidemiol 12:329-34. 2002..Various approaches for improving the success rates for sampling water from private wells are discussed, as is the use of predictive modeling to impute exposures when sampling is not feasible...

U S Geological Survey, 361 Commerce Way, Pembroke, New Hampshire 03275, USA
Environ Sci Technol 37:2075-83. 2003..89; r-squared = 0.97). On the basis of water-use information for the aquifers studied, about 103,000 people with private wells could have water supplies with arsenic at levels of concern (greater than 10 microg/L) for human health...
- Modeling the probability of arsenic in groundwater in New England as a tool for exposure assessmentJoseph D Ayotte
U S Geological Survey NH VT Water Science Center, 361 Commerce Way, Pembroke, New Hampshire 03275, USA
Environ Sci Technol 40:3578-85. 2006..Due to the complexity of the fractured bedrock aquifers in the region, well depth and related variables also are not significant predictors...
- Methyl tert-butyl ether occurrence and related factors in public and private wells in southeast New HampshireJoseph D Ayotte
US Geological Survey, Pembroke, New Hampshire 03275, USA
Environ Sci Technol 39:9-16. 2005..This finding is significant because deep bedrock wells are often considered to be less vulnerable to contamination than shallow wells, and in southeast New Hampshire, wells are being drilled deeper in search of increased supply...
